Japanese Color Atlas日本色譜きはだいろ · Amur cork yellow · family yellow
黄檗色 (Kihada-iro) is catalogued here as amur cork yellow. Yellow from Amur cork tree bark, used to dye sutra paper.
Tobunken records the underlying color/material term in the Nara-period vocabulary database derived from 『大日本古文書』; this supports historical name attestation, not measured sRGB.
Traditional color names predate modern screen color spaces, so this HEX value is a design approximation rather than a material measurement.
These entries preserve historical material, pigment, dye, or alternate-graph evidence without treating it as a direct HEX source for this color.
SOURCE BASIS Tobunken's 彩色DB records 黄檗 (Amur cork tree) as a yellow dye in the Nara-period vocabulary.
RELATIONSHIP 黄檗 is the berberine yellow dye behind 黄檗色, historically used on paper and textiles.
CAVEAT Dye-material context only. The HEX approximates a fugitive plant dye, not a measured sample.
